Make a side-by-side drawing that shows the the diffraction pattern of the single 0.04 mm slit adjacent to and at the same scale (actual size) as the interference patterns of the two pairs of 0.04 mm slits (one set spaced 0.50 mm and the other 0.25 mm) Explain what features of the two-slit pattern demonstrate the effects of both interference and diffraction.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
